ABSTRACT

A COMBINED SYSTEM AND METHOD USING LIQUEFIED NATURAL GAS FOR GENERATING ELECTRICITY AND RECOVERING POTABLE WATER FROM SALINE WATER IS PROVIDED. THAT LIQUEFIED NATURAL GAS COOLS AIR THAT IS SEPARATED TO PRODUCE OXYGEN THAT IS COMBINED WITH A PORTION OF THE VAPORIZED NATURAL GAS FOR PRODUCING ELECTRICITY PREFERABLY WITH A MAGNETOHYDRODYNAMIC (MHD) GENERATOR, ADDITIONAL REFRIGERATION AND KINETIC ENERGY GAINED FROM GAS EXPANSION ARE EMPLOYED FOR VACUUM FREEZING VAPOR COMPRESSION DESALINATION. HEAT FROM THE MHD GENERATOR MAY GENERATE STEAM FOR PRODUCING ADDITIONAL ELECTRICITY, AND ALSO HEAT WATER FOR VAPORIZATION DESALINATION. PREFERABLY A NUCLEAR REACTOR IS USED FOR PREHEATING OXYGEN AND NATURAL GAS BEFORE REACTION IN THE MHD GENERATOR.

Int. Cl. BOld 3/10 US. Cl. 203-11 1 Sheet Drawing. 8 Pages Specification A combined system and method using liquefied natural gas for generating electricity and recovering potable water from saline water is provided. The liquefied natural gas cools air that is separated to produce oxygen that is combined with a portion of the vaporized natural gas for producing electricity preferably with a magnetohydrodynamic (MHD) generator. Additional refrigeration and kinetic energy gained from gas expansion are employed for vacuum freezing vapor compression desalination. Heat from the MHD generator may generate steam for producing additional electricity, and also heatwater for vaporization desalination. Preferably a nuclear reactor is used for preheating oxygen and natural gas before reaction in the MHD gener r ISSUE OF AUGUST 19, 1975 UNDER PAT., T.M. & SEPARATES NOTICES ERRATA In the notices of Defensive Publications appearing on pages 912 in the Official Gazette of June 3, 1975, the names of the assignees were omitted and should be added as indicated below T935,001.
